IRO threadless fork

How far above the head tube does a typical IRO threadless steerer extend? I'm planning my BFFGSS group buy build. I think I'll start with the bars mounted high. My current stable of bikes has 1 inch threaded forks and not so tall stems. I have replaced the drop bars on both my current road bikes with moustache bars because I can't reach the drops comfortably. So, I'm thinking I'll try drop bars again. This time with the stem mounted high. I'll experiment with different heights for a while by changing the stack configuration. I want to know how much steerer tube extends above the head tube so I know how many stack spacers to buy.

pretty far, when i got a mark V they cut it a lot but i don't have any spacers. my roommate has one also but she's got a spacer or two. i'm thinking you'll have to cut it no matter what so get spacers to make it the height you want, and cut it down more if that's too tall.

You're bike is a mark v?
Most threadless forks that are uncut are pretty long. You go to figure they need to accomodate the largest frame size the company has to offer. I know some people that leave a an inch or two extra on the fork so they can change the spacers from above and below the stem.
If you don't want to cut your fork your bike is going to look weird and your want to buy like 8 inches of spacers. It takes about 5 minutes to cut the fork with a pipe cutter, just remember, don't cut too liberally.

buddymike - yeah, it's a mark v. i taped over all the logos as they now put them under the clearcoat but it's got the oval tubing.

i should have clarified...the "they" that cut the fork was the bike shop that helped me put it together. when i got it from IRO the fork was uncut and pretty long, it got cut a lot b/c my bike is 50cm and i didn't want spacers.

i second the not cutting too liberally. that's why i recommend you start @ the highest you think you'd want and then cut from there.

Cool. Sounds like I have all kinds of room to experiment. Maybe I'll have to cut it down some at first so I don't hit my head on the top of the steerer.

I saw on Sheldon Brown's site that he sometimes uses a pinch bolt on the steerer so he can put the handlebars up high. That lets you move the stem around all you want without messing with re-setting the fork in the headtube. Maybe I'll try that instead of a big stack of spacers while I'm experimenting.
